Definitions

  • the present invention relates to a medical needle assembly, and more specifically, relates to a special double-sided needle assembly.
  • FIG. 1 shows a conventional injector used to administer a pharmaceutical liquid into a human body, i.e., in the case where an injector already filled with pharmaceutical liquid, a so-called "pre-filled syringe" .
  • the injector shown in FIG. 1 is constructed in such a way that a conventional type double-sided needle 1 is fitted to a syringe 4 with a stopper 3.
  • a plunger (not shown) of the injector is drawn to observe back-flow of the blood, and based on the observation, an operator makes a decision whether or not the needle 1 has been inserted in the vessel of the body. However, the operator can not confirm this fact until the blood comes into the syringe 4 of the injector through the needle 1.
  • FIG. 2 shows a normal needle 5 which is also used for a syringe 7 wherein blood can be observed at a space 6 to thereby confirm the insertion of the needle 5.
  • a lead shield member 8 partially provided with a lead glass window 9 (referred to hereinafter as a "syringe shield") as shown in FIG. 3 is normally used.
  • the radiopharmaceutical in the pre-filled syringe is administered through the use of the syringe shield 8, the operators confirm entry of blood through the glass window 9 thereof.
  • it is very difficult to observe the inside of the syringe because of the yellowish color of the glass window 9, which is not a colorless transparent color, and the darkness inside of the syringe.
  • a luer cap 2 namely a double luer needle 10
  • a disposable needle (not shown)
  • the length of the needle portion thereof composed by the double luer needle 10 and the disposable needle is increased, resulting in difficulty in administering a pharmaceutical liquid.
  • the needle shown in FIG. 5 the technique for performing a firm engagement between a double luer needle 11 and a luer cap 2 is difficult, and even though the engagement is performed, it results in a very high cost lacking practical use.
  • an essential object of the present invention is to resolve these disadvantages and to provide a double-sided needle assembly which reduces the length of the needle portion thereof, and is capable of easily being fitted to a syringe of an injector, resulting in a compact construction, and accomplishing confirmation.
  • a double-sided needle assembly comprising: an insert needle for inserting into a vessel; an afflux needle for supplying pharmaceutical liquid in a syringe of an injector to the insert needle; and a transparent luer member connecting the insert needle with the afflux needle through a space defined between an end of the insert needle and an end of the afflux needle in the luer member, and holding the insert and afflux needles to fit to the syringe.
  • the space for observing the back-flow of blood is arranged between the end of the insert needle and the end of the afflux needle in the luer member, confirmation of insertion of the insert needle into a vessel can be conveniently accomplished through the space in the luer member. Then, in the case of administration of pharmaceutical liquid, the radiation exposure of the operators can be certainly reduced by the use of the needle assembly. Furthermore, the length of the needle portion composed by the insert needle and the afflux needle is as small as that of a conventional normal disposable needle.
  • the needle assembly can be very compact in construction, and can be fitted to a syringe of an injector by pressing at one time for completion for preparation of the use.
  • FIG. 1 is a partial sectional view of an injector fitting a double-sided conventional needle to a pre-filled syringe;
  • FIG. 2 is a partial sectional view of an injector fitting a normal needle to a normal syringe
  • FIG. 3 is a perspective outside view of a syringe shield
  • FIGS. 4 and 5 are partial sectional views of injectors fitting improved double luer needles to pre-filled syringes, respectively;
  • FIG. 6 is a sectional view of a double-sided needle assembly of a preferred embodiment according to the present invention.
  • FIG. 7 is a sectional view of the upper end of an afflux needle of the needle assembly shown in FIG. 6;
  • FIG. 8 is a sectional view of a double-sided needle assembly of another embodiment in which small needles are fitted to both ends of a transparent cylinder;
  • FIGS. 9 and 10 are sectional views in the conditions where the needle assembly with the small needles is being inserted into and is fitted to a transparent luer;
  • FIG. 11 is an enlarged sectional view of a luer member having a space partially defined therein and holes for adhering needles;
  • FIG. 12 is a sectional view of an injector complete for use which has a double-sided needle assembly of another embodiment fitting needles to a pre-filled syringe.
  • the kind of parts of a double-sided needle assembly of the preferred embodiment according to the present invention is generally the same as that of a commercial disposable needle, except for a cylinder 14 and an afflux needle 15.
  • the assembly is manufactured in a similar manner.
  • the needle assembly includes an insert needle 12 for inserting into a vessel; an afflux needle 15 for supplying pharmaceutical liquid in an injector (not shown) to the insert needle 12; and a transparent luer member 13.
  • the luer member 13 connects the insert needle 12 with the afflux needle 15 through a space 17 defined in the luer member 13, and holds both needles 12 and 15 to fit to the syringe of the injector. Therefore, the luer member 13 has a tapered hole for fitting to the syringe at the lower portion thereof in FIG. 6.
  • the luer member 13 has a lower hole for inserting the afflux needle 15, and an upper hole for inserting the insert needle 12.
  • the luer member 13 preferably has a rib 16 for preventing the afflux needle 15 from easily slipping off from the luer member 13 after the insertion of the afflux needle 15 into the luer member 13.
  • the afflux needle 15 is shown in FIG. 7 and is manufactured separate from the other parts.
  • a cylinder 14, serving as a connecting member, is fixed to the upper end of the afflux needle 15 in FIG. 6.
  • the lower end of the insert needle 12 is fixedly inserted into the upper hole of the luer member 13 in FIG. 6.
  • the cylinder 14 of the afflux needle 15 is fixedly inserted into the lower hole of the luer member 13.
  • the cylinder 14 adheres to the luer member 13 to define the space 17 between the lower end of the insert needle 12 and the upper end of the afflux needle 15 in the luer member 13. If the luer member 13 can be fixedly connected with the cylinder 14, the adhesive and/or the rib 16 is unnecessary. The luer member 13 is fitted to the syringe of the injector.
  • the space 17 for observing the back-flow of blood is arranged between insert needle end and the afflux needle end in the transparent luer member 13, the confirmation of the insertion of the insert needle 12 into a vessel can be conveniently performed through observation of the space 17 of the luer member 13. Then, in administering pharmaceutical liquid, the radiation exposure to the operators can be certainly reduced by the use of the double-sided needle assembly. Furthermore, the length of the needle portion composed by the insert needle 12 and the afflux needle 15 is as small as that of a conventional normal disposable needle and also the double-sided needle assembly can be very compact in construction. The double-sided needle assembly can be fitted to the syringe of the injector by pressing at one time for completion for preparation of the use.
  • an insert needle 12 is previously connected with an afflux needle 15 through a transparent cylinder 18 to be integral with each other so that the space 17 can be defined between the needles 12 and in the cylinder 18.
  • these small double-sided needle parts are inserted into and adhered to a transparent luer 22, with the result that a similar needle assembly can be manufactured as the needle assembly of the first embodiment.
  • the luer member 21 is composed of the cylinder 18 and the luer 22. It is possible that the small double-sided needle parts shown in FIG. 8 can be inserted into the pre-filled syringe type luer cap 2 shown in FIG. 1 to obtain the same advantage as the embodiments.
  • the space 17 is previously formed in a transparent luer member 23 by one-piece molding. Thereafter, the insert needle 12 is inserted into an upper hole 23a thereof and the afflux needle 15 is inserted into a lower hole 23b thereof, with the result that a double-sided needle assembly of another embodiment can be manufactured.
  • the luer members 13, 21, and 23 and the cylinder 14 can be made of plastic material such as polypropylene or polystyrene.
  • plastic material such as polypropylene or polystyrene.
  • adhesives widely used in normal disposable needles can be employed.
  • adhesives used in normal plastic adhesion can be employed, but more preferably, both are adhered by ultrasonic welding in order to avoid to the utmost, any adverse effect to pharmaceutical liquid.
  • the size and length of the space 17 for observing the blood in the luer members 13, 21, and 23 is not limited as above-described, but can be modified within the scope of the present invention.
  • the use of the special double-sided needle assembly will be described in employing the needle assembly shown in FIG. 6.
  • the needle assembly is inserted into the pre-filled syringe type luer cap 2 in FIG. 1 under pressure and a piston member 19 is attached to a rubber plunger 20 to be inserted into the syringe 4, resulting in completion and preparation for use.
